[The diagnostic contribution of computed tomography in a case of volvulus of the small intestine after an ileoanal anastomosis].

A case of acquired volvulus as a cause of late small bowel obstruction, in a patient who had undergone a colectomy with ileal pouch-anal anastomosis two years previously, is described. Computed Tomography (CT) accurately demonstrated signs of adhesive strangulating obstruction, detecting also a radial disposition of the loops around the mesenteric root and an abnormal position of the superior mesenteric artery and vein on the right side of the aorta. From a literature survey, there are no previous studies reporting the CT appearance of a small intestine volvulus developed as a complication of an ileal pouch-anal anastomosis.
